ABSTRACT

The article presents scientific data on the effect of chelated micro-fertilizers on the formation of productivity elements of sorghum grain varieties. The experiments were conducted in the period from 2021 to 2023, in the fields of the Scientific Research Institute in the city of Saratov, Saratov region. The purpose of the field experiments was to identify the effect of chelated micro-fertilizers on the elements of the sorghum crop structure and provide an economic assessment of their use. The results of the study showed that leaf treatments of vegetative plants of grain sorghum with chelated preparations led to a significant increase in the mass of 1000 grains, grain yield and biomass yield. The use of fertilizers in chelated form in sorghum crops was economically beneficial and cost-effective in all the experimental variants studied, which is clearly shown in the tables below. Based on the above, it can be concluded that the use of chelated micronutrients of a new generation as leaf fertilizers during the growing season when growing grain sorghum is an important agricultural technique for obtaining a consistently high yield of seeds and biomass, with proper selection of optimal doses and timing of use of drugs, it is possible to obtain up to 57-126% increase in grain yield and up to 30-33% of biomass yield. Leaf treatments of sorghum plants during the growing season with chelated micro–fertilization turned out to be profitable for a number of varieties - Assistant (187.4%), Pendant (340.2%) and Prince (400.6%), Magister and RSK Cascade, the profitability level reached 224.0-231.9%, respectively, at RSK Locus and Garant, the profitability of cultivation of which increased to 144.94 -192.3%, respectively.
